Sheffield United boss Paul Heckingbottom has been in talks with former Manchester United defender Axel Tuanzebe.
The newly-promoted Premier League side have also opened talks with Arsenal for defender Auston Trusty.
The Blades are pursuing a loan deal for the USA international who was player of the year at Birmingham City last season and, as Confidential readers will know, was a target for Rangers earlier this summer.
Sheffield United are keen to get the deal for Trusty over the line, and are set to receive a financial injection from the sale of Iliman Ndiaye to Marseille for £18million.
